Hi Guys I`m from Costa Rica, this is my project, My car is an Evo VI JDM

This is my mods:

2.0 Engine with Evo 9 pistons and rods. 135psi per cilinder compression.
No balance shafts
GT3076R ATP turbo
Stock manifold
Injen Intake with samco air filter
2,5 intercooler pipes
3" big intercooler 28x11.75x3 Megan Racing
kelfords 272 cams
hks valve springs
ARP head studs
720cc injectors
Walbro 255lph fuel pump
Evo 8 ECU with ralliart rom retuned at .8 bar
Complete exhaust in 3"
38mm wastegate

In this moment my car not was tuned at 14 psi because my tuner had problems to log the ECU tune at 14psi(the tuner does not know much about tuning evos), any way this dyno sheet was at 14psi but the AFR is too bad at 10s or less. My car in one run made 305whp at 11psi.



I want to reach the 400whp, what I need??? how many psi need to achieve my goal? here in my country the fuel have 93-95 octane, Is possible to make 400whp safe in my project, I have many questions at this time hope the good people in this forum can help me to finish my project.

Thanks for any help.

 

The dyno sheet of 335whp was at 14psi with problems in the mixture.

 

On the HTA 3076 (not the ATP I realise) we made 423 at 23psi in a road race setup that was somewhat similar to yours. Normally it seems a 3076 will be 400-440 depending on octane of fuel. What fuel is going in the car, 93-95 MON or RON?

you might want to try another tuner if your tuner does not know much about tuning evos. you can do a remote tune. i have been very please with my results. http://mellontuning.com/

Get a different tuner that knows what he's doing. Nice video man lol
